Must You Go? (2021)

Min Yoo Jung (Park Jung Yeon) is a 25-year-old woman who dreams of becoming a successful pop musician. But her musical dreams are a long way from coming true - and she spends her evenings busking on the streets. Life takes a turn for the weird when Park Yeon (Chani), a talented musician from the past is transported from the Joseon Dynasty (1392-1910) to the present day, where he meets Min Yoo Jung and indicates he is ready to help her on her musical quest. However, he is not the only time-traveling visitor to drop in on her: A gifted vocalist by the name of Lee Won (Lee Seung Hyub) also travels from the distant past and makes her acquaintance.
